"illrliTED PATRICK H. MCGRATH, OF WOLLASTON, MASSACHUSETTS, ASSIGNCR OF ONE-HALF TO CHARLES H. WHITAKER, OF BROOKFIELD, MASSACHUSETTS.

WINDOW-SASEI FASTEILHNG.

To all whom it may concern:

Be it known that l, PATRICK H. MCGRATH, a citizen of the United States, residing at Wollaston, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in W indow-Sash Fastenings, of which the following is a specification.

This invention relates to window sash fastenings, the object of the invention being to provide a simple and effective device of this character which can be easily and inexpensively made.

ln the drawings accompanying and forming part of this specication l showin detail certain convenient forms of embodiment of the invention which, to enable those skilled in the art to practice the same, will be set forth in detail in the following description, While the novelty of the invention will be included in the claims succeeding said description.

Referring to the drawings: Figure 1 is a perspective view of a sash provided with fastening means including my invention. Fig. 2 is an edge view of the upper portion of the same. Fig. 3 is a perspective view of the lower portion of the fastening member. Fig. 4 is a face view of a modified form of fastening means, and Fig. 5 is a top plan view of the same.

Like characters refer to like parts throughout the several iigures of the drawings.

Referring first to Figs. l, 2, and 3, wherein one of the forms of the invention is represented, the numeral 2 denotes a window sash which may be made of any suitable material, size, or shape. l have shown as formed in an edge of the sash 2 a vertically extending rabbet as 3 in which is litted a fastening member as 4. rihe fastening member is represented as consisting of an elongated strip which at all times extends above the top of the sash, the lower end of said strip extending short of the corresponding portion of the sash. In the present case this strip 4 has two reciprocatory movements, one in a vertical direction, and the other, in a horizontal direction. The movements are of such a character, however, that the strip moves in a diagonal direction in performing one complete cycle of operations. The rabbet 3 in Patented Jan. l2, 1909.

the present instance is located in the inner side of the sash 2 and is approximately half the depth of the sash. The width of the strip 4 is substantially the same as that of the rabbet or angular channel 3. This fastening member or strip 4 cooperates in the present case with the customary stop forming part of a window frame, although it may coact with any other desirable part to fasten the window sash in a desired adjusted position.

The vertical reciprocation of the fastening member or strip 4 is accomplished by two factors, one, a suitable positive means, and the other, manual operation. The positive any desirable nature, such for example as a flat spring as 5 fastened at its shank or butt by screws or otherwise to the top of the sash 2. The free end ofthe spring 5 bears against the under side of a projection or pin as 6 extending outward from the fastening member or strip 4, the tendency of the spring being to elevate or upwardly thrust the fastening member or strip 4. Said stripl 4 is shown as provided near its lower end with an inwardly projecting lug 7 which enters a notch as S in the hub of a pivotally mounted actuator or lever as 9 represented as supported for swinging movement by a bracket as 10 fastened to the inside face of the sash 2 in proximity to the lug 7. Said actuator or lever swings in a plane substantially parallel with the inner face of the sash by reason of which compactness is obtained. The hub of the hand lever or actuator 9 is provided with a lug or ear as li cooperative with a similar part as 12 extending from the bracket or plate l0. The fastening member 4 is shown in its upper position in Fig. l, being thus held by the spring 5. When the long arm of the lever 9 is grasped and is thrust upward it will be clear that the fastening member 4 will be drawn downward by virtue of the engagement of the upper wall of the notch 8 with the lug or projection 7. When this is done the pin or projection 6 by acting against the spring 5 will bend or flex the free portion of said spring downward.' lilhen the actuator or lever 9 is released the fastening member or strip 4 will also be released whereby the spring 5, by reaction or relaxation, is adaptmeans for actuating said member 4 may be of ed to elevate the fastening member 4 or to return the same to its initial condition, as indicated in said Fig. 1. l have described but one rabbet or channel 3 and one fastening member or strip 4 and the parts which coperate with the latter. These devices and certain others to be hereinafter described may be duplicated at the opposite side of the sash. For simplicity of illustration and description, however, I have shown only one fastening member and its adjuncts.

Means are cooperative with the fastening member 4 for causing a lateral, horizontal, or transverse motion thereof during the endwise or longitudinal movement of the same, and this means may be of any suitable character although 1 have found cam devices as satisfactory for my purpose. The inner side of the fastening member 4 is represented as provided with a plurality of wedges each denoted by 13. There may be any number of these wedges and they may be separated any desirable distances apart. They cooperate with wedges as 14 fastened to the bottom of the rabbet or channel 3. Said Wedges 13 and 14 are respectively separate from the .fastening strip and sash by reason of which inexpensiveness and lightness can be obtained in that wood can be readily employed in the make-up of the sash and said fastening strip while the Wedges may be of metal and may be fastened to the said arts in any suitable way, for illustration by s iort screws. The wedges 14, by acting against the wedges 13, cause a lateral motion of the fastening member 4 either outwardly to cause said fastening member to assume a fastening relation, or inwardly to cause said fastening member to assume an inoperative or releasing position. 1n Figs. 1 and 2 the fastening member 4 is shown at the limit of its upward movement and the effective face of the wedge 13 is against the corresponding face of the wedge 14, the strip 4 at this time being held by the wedgeV 14 away. from the bottom of the rabbet 3 and solidly against a window stop or equivalent part so as to securely fasten the sash 2. '.lo release said sash the member 4 is drawn downward by the action of the lever 9 in the manner hereinbefore described and, when this downward motion takes place, the active faces of the wedges 13 ride downwardly and outwardly along the active faces of the wedges 14 whereby the member or strip 4 can be freed from the window stop or other part to permit the raising, lowerin or other adjustment of the sash 2. When t 1e adjustment is obtained the lever 9 is released and the spring 5 becomes immediately effective for lifting the fastening member or strip 4, while at the same time the Wedges 14 act to positively move the fasten- 'ing .member or strip 4 in an inward direction and'solidly against -a window stop or equivalent part to securely fasten the sash in a tightmanner. i/Vhile the sashis maintained normally in such relation it can readily be raised or lowered in a simple manner, all as 'clearly brought out.

1t will be clear, therefore, that my invention contemplates a window sash provided with a fastening member and means associated with said fastening member and operative when said member is advanced for causing the same to move toward a fastening or operative position. The advancing movement of the fastening member or strip in the present case is upward. r1`he movement of the fastening member or strip toward or from its operative position is, as will be understood, transverse to the advancing or endwise movement of the strip and is accomplished by devices which are not connected with each other but which are carried by the fastening member and sash respectively. The fastening motion of the fastening member is accomplished in a frictional manner which, as stated, may be advantageously secured by cooperating cams or wedges.

1n Figs. 4 and 5, the main difference between tne form of the invention represented thereby and that hereinbefore described is in the spring. rEhe sash 2iL in said Figs. 4 and 5 has a rabbet 3a in which is mounted the fastening member 4a having near .its lower end a projection as 7 a engageable by a projection as 8a on the hub of the hand lever 9a pivoted to a bracket as 10a fastened to said sash 2a. rhere isV represented as extending downward from the top of the sash 2iJL a bore or hole 15 in which is located a coiled pull spring as 16 the upper end `of which is suitably connected with a fixed but Aton as 17 'fitted in the top of said bore or hole 15, while the lower end of the spring is connected with a hook as 17a on a plate as 13 attached to the strip 4a at the upper portion thereof.v rThe spring 16 performs the same function as the spring 5. The rabbet 3@ is connected with the bore or hole 15 by a slot as 19 in which the hook 17'a and its shank can freely move vertically during lthe up and down operation of the member or strip 4a.

I have described two ways in which the invention may be advantageously carried into effec Other ways can be adopted for obtaining this result within the scope of my claims.

What 1 claim is:

1. The combination of a window-sash, a holding strip carried by said sash, separate sets of cooperating wedges distinct from the sash and strip respectively, and fastened thereto, and a spring for moving said strip in an endwise direction, the two sets ,off wedges cooperating during the endwise movement of the strip to cause lateral metion ofthe latter.
